-GNU General Public License for more details.
-
-You should have received a copy of the GNU General Public License
-along with this program.  If not, see <http://www.gnu.org/licenses/>.
-
-
-GENERAL INFORMATION:
-
-This is a PHP Chat based on LE CHAT v.1.14. An up-to-date copy of this script can be downloaded at https://github.com/DanWin/le-chat-php
-The original perl LE CHAT script by Lucky Eddie can be downloaded at http://4fvfamdpoulu2nms.onion/lechat/ or via a tor2web proxy like https://4fvfamdpoulu2nms.tor2web.blutmagie.de/lechat/ if you don't have TOR installed.
-If you add your own cool features or have a feature request, please tell me and I will add them, if I like them.
-Please also let me know about any bugs you find in the code, so I can fix them.
-Now a piece of information about the origin of the name "LE CHAT" copied from the original script:
-The "LE" in the name you can take as  "Lucky Eddie", or since the script was meant to be lean and easy on server resources, as "Light Edition".
-It may even be the French word for "the" if you prefer. Translated from French to English, "le chat" means: "the cat".
-
-FEATURES:
-
-Optimized for TOR
-No JavaScript
-Cookies supported, but not needed
-Captcha
-Multiple languages
-Members and guests
-Waiting room for guests
-Moderatoral approval of new guests
-Public, member, moderator and admin only chats
-Private messages
-Multi-line messages
-Change font, colour and refresh rate in profile settings
-Autologout when inactive for some time
-Image and video embedding
-Notes for admins and moderators
-Clone the chat to have multiple tabs
-Kick chatters
-Clean selected messages
-Clean the whole room
-Plain text message filter
-Regex message filter
-And more
-
-INSTALLATION INSTRUCTIONS:
-
-You'll need to have mysql, php and a web-server installed. For the captcha feature, you also need php5-gd.
-When you have everything installed, you'll have to create a database and a user for the chat in mysql.
-Then edit the configuration at the bottom of the script to reflect the appropriate database settings and to modify the chat settings the way you like them.
-Then copy the script to your web-server directory and call the script in your browser with a parameter like this:
-	http://(server)/(script-name).php?action=setup
-Now you can create the Superadmin account. With this account you can administer the chat and add new members and set the guest access.
-As soon as you are done with the setup, all necessary database tables will be created and the chat can be used.
-Note: If you updated the script, please visit http://(server)/(script-name).php?action=setup again, to make sure, that any database changes are applied and no errors occure.
-
-TRANSLATING:
-
-Copy lang_en.php and rename it to lang_YOUR_LANGCODE.php
-Then edit the file and translate the messages into your language.
-If you ever use a ' character, you have to escape it by using \' instead or the script will fail.
-When you are done, you have to edit the chat script, to include your translation. Simply add a line with
-		'lang_code'	=>'Language name',
-to the $L array in the load_lang() function at the bottom, similar to what I did for the German translation.
-Please share your translation with me, so I can add it to the official version.
-
-REGEX:
-
-Yes, the chat supports regular expression filtering of messages. As regex tends to be difficult for most people, I decided to give it an extra section here.
-Regex is very powerful and can be used to filter messages that contain certain expressions and replace them with something else.
-It can be used e.g. to turn BB Code into html, so it is possible to use BB Code in the chat to format messages.
-To do this, use this Regex-Match '\[(u|b)\](.*?)\[\/\1\]' and this Regex-Replace '<$1>$2</$1>' and your text will be '[b]bold[/b]' or '[u]underlined[/u]'.
-You can also use smilies by using this Regex-Match '(?-i::(cry|eek|lol|sad|smile|surprised|wink):)' and this Regex-Replace '<img src="/pictures/$1.gif" alt=":$1:">'
-And now if you enter ':smile:' an image with the smiley will be loaded from your server at '/pictures/smile.gif'.
-The following should be escaped by putting '\' in front of it, if you are trying to match one of these characters '/ \ ^ . $ | ( ) [ ] * + ? { } ,'.
-I used '/' as delimiter, so you will have to escape that, too. The only options I used is 'i' to make the regex case insensitive.
-If you want to test your regex, before applying you can use this site and enter your Regex and Replacement there and click on preg_replace: http://www.phpliveregex.com/
-If you never used regex before, check out this starting guide to begin with regular expressions: http://docs.activestate.com/komodo/4.4/regex-intro.html
-
-LIVE DEMO:
-
-If you want to see the script in action, you can visit my TOR hidden service http://tt3j2x4k5ycaa5zt.onion/chat.php or via a tor2web proxy like http://tt3j2x4k5ycaa5zt.tor2web.blutmagie.de/chat.php if you don't have TOR installed.
-Considering this is a hidden service, you should be prepared for the worst case, as people often tend to do illegal activities in the TOR network. I'm not online 24/7 so it might not be possible to remove such content right away.
-If you should see illegal content, don't panic. Use the contact form on my site to notify me and clean your browser cache afterwards.

+Optionally, you can install:
+- the gd extension for the captcha feature
+- the json extension for save/restore
+- the intl extension for browser language detection
+- a memcached server and the memcached extension and change the configuration to use memcached. This will lessen the database load a bit.
+- a MySQL or PostgreSQL server to use as an external database instead of SQLite

+Translations are managed in [Weblate](https://weblate.danwin1210.de/projects/DanWin/le-chat-php).
+If you prefer manually submitting translations, the script `update-translations.sh` can be used to update the language template and translation files from source.
+It will generate the file `locale/le-chat-php.pot` which you can then use as basis to create a new language file in `YOUR_LANG_CODE/LC_MESSAGES/le-chat-php.po` and edit it with a translation program, such as [Poedit](https://poedit.net/).
+Once you are done, you can open a pull request, or [email me](mailto:daniel@danwin1210.de), to include the translation.
